Abstract
This paper describes the noise interference generated by the power supply of the heating wire,and proposes a method for suppressing interference in pipeline corrosion detection under the insulation layer containing the heating wire.At a fixed sampling time,it can identify the direction of the heating wire and its impact on the detection signal by comparing the receiving response of each probe at the sampling time.
